The housing crisis in Cumberland County has intensified, with the rental vacancy rate falling to a historic low of 1.2 percent — well below the 5 percent threshold considered a healthy, balanced market — according to a new report from the Maine Housing Authority.
The report paints a stark picture of a market where demand vastly outstrips supply, driving rents to levels that strain even middle-income households. The average rent for a two-bedroom apartment in the Portland metro area has risen to $1,850 per month, an increase of 32 percent over the past five years.
“We are in a full-blown housing emergency,” said Maine Housing Authority director Dan Brennan. “Working families, seniors, young professionals — people across the income spectrum are struggling to find housing they can afford in southern Maine.”
The crisis is driven by a combination of insufficient housing production, strong demand from a growing population, the conversion of long-term rental units to short-term vacation rentals, and construction costs that make new affordable housing development financially challenging.
Portland has seen particularly acute pressure. The city’s population has grown by approximately 5 percent since 2020, driven by remote workers relocating from higher-cost cities, immigrants and refugees, and the natural draw of the city’s quality of life. But housing construction has not kept pace, with only about 350 new units permitted annually compared to an estimated need of 600 to 800.
The impacts are far-reaching. Local employers report difficulty recruiting and retaining workers who can’t find affordable housing. Teachers, healthcare workers, restaurant staff, and first responders increasingly commute from outlying communities, adding to traffic and reducing their quality of life.
“I have employees driving 45 minutes each way because they can’t afford to live anywhere near Portland,” said restaurant owner Maria Gonzalez. “It’s not sustainable.”
Municipalities across the county are responding with zoning reforms designed to encourage more housing development. Portland recently approved a comprehensive zoning overhaul that allows greater density in residential neighborhoods, while South Portland and Westbrook have streamlined permitting for multifamily housing.
Advocacy groups are also pushing for stronger tenant protections and policies to limit the conversion of housing to short-term rentals. “We need to both build more and protect what we have,” said Maine Affordable Housing Coalition director Greg Payne.
